Technologies

Ice TECHNOLOGIES
The fade, which can occur to rotor and pad when braking on a long downhill ride for instance, has a negative impact on the braking performance. SHIMANO has adopted ICE TECHNOLOGY Rotor and ICE TECHNOLOGY Pad to realize the cooling technology for consistent performance. The clad rotor blade, which has a 3 layer-sandwich structure of stainless steel, aluminum and stainless steel, provides better radiation performance achieving from 400˚C to 300˚C surface temperature. Also, the radiation fin has been adopted for the pad. Moreover, the clad rotor blade and the radiator fin provide long pad life, less noise, less fade and lightweight.
Center Lock System
The CENTER LOCK system makes an easy rotor installation possible with spline mount and a lock ring. The lock ring mounting system reduces the total working hours by shortening the amount of time of both installation and de-installation. In addition, the secure fixing by the spline mount enhances precision and rigidity while improving braking efficiency.
